I am starting prednisolone 20mg a day today and am really worried about side effects. I am most concerned about weight gain (as I am already overweight) and mood swings. Has anyone had any success in coping with those? Does the weight gain just happen without you doing anything or can you limit it through diet and exercise? I've seen my daughter when on steroids for her asthma and she gets quite manic - I dread the thought of being out of control like that in front of my kids. Anyone have any advice or experience to share? Thanks so much.
